Chapter 20, Problem 15TY
Summary Introduction
Introduction:
Genetic engineering is the modification of an organism’s genome to introduce a trait, which would not have inherently been present in it. It has opened up new frontiers for scientists giving them the ability to create transgenic bacteria, plants, and even animals. Transgenic bacteria have become biological factories to produce desirable substances for our benefits.
